I wanted to insert data in a table from a text file where it is stored in csv format to a sql server table. For that, I am using bulk-insert statement. Now I need to specify the file name in "From" clause. I don't want to use networked locations or local locations over there. I want to upload my text file in the same directory as my executable file and give a relative path to it. Is it possible???
I don't think so. I just tried
SELECT BulkColumn
FROM OPENROWSET(BULK'files\doesnotexist.txt',SINGLE_BLOB)x;
And looked at it in Process Monitor
And it was looking for C:\WINDOWS\system32\files\doesnotexist.txt so I think you would need to put in the full path.

Start situation:
a folder with lots of files (images mostly png).
two tables in database (MariaDB) which contains supposed image filenames. I query the filenames like this:
select filename from table1
UNION
select filename from table2;
I want to know if I have files not registered in the database tables.
My first approach is to put the list of filenames inside a textfile (I've used Linux command line, list is filename per line), but I don't know how to continue.
I can't write in the database. UPDATED. I got more auth to perform my job tasks. Therefore I solved this with the suggestion.
You need to do couple of things:
Import the file with list of files into the database.
Use cursor to go through the list of file names and match it to your table list which contains the list-b of file names
To import file name you can use the import method or directly read the file as a table virtually.
Thanks
I want to read a tab delimited file using PLSQL and insert the file data into a table.
Everyday new file will be generated.
I am not sure if external table will help here because filename will be changed based on date.
Filename: SPRReadResponse_YYYYMMDD.txt
Below is the sample file data.
Option that works on your own PC is to use SQL*Loader. As file name changes every day, you'd use your operating system's batch script (on MS Windows, these are .BAT files) to pass a different name while calling sqlldr (and the control file).
External table requires you to have access to the database server and have (at least) read privilege on its directory which contains those .TXT files. Unless you're a DBA, you'll have to talk to them to provide environment. As of changing file name, you could use alter table ... location which is rather inconvenient.
If you want to have control over it, use UTL_FILE; yes, you still need to have access to that directory on the database server, but - writing a PL/SQL script, you can modify whatever you want, including file name.
Or, a simpler option, first rename input file to SPRReadResponse.txt, then load it and save yourself of all that trouble.
I'm trying to find a specific string on my database. I'm currently using FlameRobin to open the FDB file, but this software doesn't seems to have a properly feature for this task.
I tried the following SQL query but i didn't work:
SELECT
*
FROM
*
WHERE
* LIKE '126278'
After all, what is the best solution to do that? Thanks in advance.
You can't do such thing. But you can convert your FDB file to a text file like CSV so you can search for your string in all the tables/files at the same time.
1. Download a database converter
First step you need a software to convert you databse file. I recommend using Full Convert to do it. Just get the free trial and download it. It is really easy to use and it will export each table in a different CSV file.
2. Find your string in multiple files at the same time
For that task you can use the Find in files feature of Notepad++ to search the string in all CSV files located at the same folder.
3. Open the desired table on FlameRobin
When Notepad++ highlight the string, it shows in what file it is located and the number of the line. Full Convert saves each CSV with the same name as the original table, so you can find it easily whatever database manager software you are using.
Here is Firebird documentation: https://www.firebirdsql.org/file/documentation/reference_manuals/fblangref25-en/html/fblangref25.html
You need to read about
Stored Procedures of "selectable" kind,
execute statement command, including for execute statement variant
system tables, having "relation" in names.
Then in your SP you do enumerate all the tables, then you do enumerate all the columns in those tables, then for every of them you run a usual
select 'tablename', 'columnname', columnname
from tablename
where columnname containing '12345'
over every field of every table.
But practically speaking, it most probably would be better to avoid SQL commands and just to extract ALL the database into a long SQL script and open that script in Notepad (or any other text editor) and there search for the string you need.
I'm trying to use oracle external tables to load flat files into a database but I'm having a bit of an issue with the location clause. The files we receive are appended with several pieces of information including the date so I was hoping to use wildcards in the location clause but it doesn't look like I'm able to.
I think I'm right in assuming I'm unable to use wildcards, does anyone have a suggestion on how I can accomplish this without writing large amounts of code per external table?
Current thoughts:
The only way I can think of doing it at the moment is to have a shell watcher script and parameter table. User can specify: input directory, file mask, external table etc. Then when a file is found in the directory, the shell script generates a list of files found with the file mask. For each file found issue a alter table command to change the location on the given external table to that file and launch the rest of the pl/sql associated with that file. This can be repeated for each file found with the file mask. I guess the benefit to this is I could also add the date to the end of the log and bad files after each run.
I'll post the solution I went with in the end which appears to be the only way.
I have a file watcher than looks for files in a given input dir with a certain file mask. The lookup table also includes the name of the external table. I then simply issue an alter table on the external table with the list of new file names.
For me this wasn't much of an issue as I'm already using shell for most of the file watching and file manipulation. Hopefully this saves someone searching for ages for a solution.
I'm trying to write a SQL script, that can be transferred to another computer and someone else will get a whole database with no problem.
What I'm fighting with, is how to make a relative path for an image?
Let's say, that someone will have a script in c:\Documents\script.sql
But I don't know that if someone will keep it there.
I have a folder with images, that I want to load to my database
So here's a fragment of my script, how to make a relative path? Let's say that images/ and script.sql are in the same folder
INSERT dbMagazynier.dbo.Produkty (Nazwa, Cena, Opis, Zdjecie, ID_Producenct)
SELECT 'jeansy', 199.00, 'jenasy jak na zdjeciu', Zdjecie.*, 5
FROM OPENROWSET (BULK '\images\jeansy.jpg', SINGLE_BLOB) Zdjecie
BUT SQL Server 2012 says that it can't find my jeans image
I don't believe you can work with relative paths in SQL Server. You can check more in this question: Relative path in t sql?
The best you can do is to declare a variable at the top of the script, specify the file location there and use your variable later in the code of the script. You can also put some comments about the variable with instructions for people using the script.
